[Bug 1457526] Re: recognized partitions incomplete on 14.04.2 and 15.04

 

How large is this sd card supposed to be, and how large does it appear
under 12.04?  Because right now it appears to be just under 16 GB which
is not large enough to hold the partitions listed in the partition
table.  The output of lsblk from both the working and non working kernel
would be helpful.

Title:
  recognized partitions incomplete on 14.04.2 and 15.04

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  on ubuntu 15.04, 14.04.2 the system shows me after plugging a SD card
  the following information (where sdc the SD card is)

  me@my-Linux:~$ cat /proc/partitions
  major minor  #blocks  name
  ...
     8       32   15558144 sdc
     8       33    3807232 sdc1

  me@my-Linux:~$ sudo fdisk -l /dev/sdc
  Disk /dev/sdc: 14,9 GiB, 15931539456 bytes, 31116288 sectors

  /dev/sdc8       14008320 31047679 17039360   8,1G 83 Linux

  Partition table entries are not in disk order.

  none of the partitions are able to mount.

  
  the exact same SD card and same USB/SD card reader but using ubuntu 14.04 or 12.04 shows me the correct information:
  me@my-Linux:~$ cat /proc/partitions
  major minor  #blocks  name
  ...
     8       16   15558144 sdc
     8       17     121046 sdc1
     8       18          1 sdc2
     8       19      32768 sdc3
     8       21     163840 sdc5
     8       22    6639616 sdc6
     8       23      61440 sdc7
     8       24    8519680 sdc8

  tested environments:
  with that issue (wrong/incomplete partition information)
  ubuntu 15.04 amd64 (dist-upgraded from 14.10 to 15.04)
  ubuntu 15.04 liveDVD amd64 (from 2015)
  ubuntu 14.04.2 liveDVD amd64 (from 2015)

  without that issue (correct partition information)
  ubuntu 12.04 liveDVD amd64
  ubuntu 14.04 liveDVD amd64 (~2014)
  debian 8.0.0 liveCD amd64 LXDE (from 2015)
